Tire inspection device. |
摘要 |
<p>The present invention provides a device for inspecting the pressure, temperature, etc. in the tire (1) and which is composed of a pressure sensor (9) attached to the valve (4) fixed to the tire fixing rim (2) and of which the output varies depending upon the tire internal pressure and a resonator (10) including a resonant coil (8) which resonates with an external radiation electromagnetic wave and a capacitor. The oscillation coil (30) of an oscillator (24) which generates the above-mentioned radiation electromagnetic wave is installed as projected from the main body (20) in which the main body (20) of the inspection device comprises a signal processor (25) which detects and processes any change in oscillation state which has take place at the oscillator as caused by the resonance state of the resonator (10) and a display (26) to display the result of the processing made at the signal processor (25).</p> |
